Stevenage new striker Calvin Zola is set to miss their League Two opener against Hartlepool on Saturday.
The 29-year-old, who signed from Aberdeen earlier this summer, has been suffering from a hamstring injury.
“He’s approaching fitness. It’s one of those when we have got to manage the long term picture in Calvin’s case. He’s come back a couple of times with a strain and it’s broken down on him,” said Stevenage manager Graham Westley, speaking to The Advertiser.
“We want to make sure we give him every chance of a strong season and putting more time into him now in terms of rehabilitation is probably a wise thing to do.”
The Hertfordshire Club are already without Simon Walton, who is still suspended and Ronnie Henry (Knee) Chris Beardsley and midfielder Dan Parrett (Knee).
